Hybrid Tea rose plant named `sellobby`

ABSTRACT

A new rose variety of the Hybrid Tea class, characterized by its continuous and profuse production of medium-sized soft pink flowers, borne singly on upright stems on a sturdy bush of medium height, having abundant and glossy foliage and a weak fragrance.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the Hybrid Tea class, which was originated by me by crossingthe variety "Jacaranda" with an unnamed (SR 85.055) and unpatentedseedling.

The primary objective of this breeding was to obtain a new rose varietycomparable to that of "Jacaranda" with a smaller in size and more softpink flower and same fragrancy. While the results achieved a distinctpink hybrid tea rose of smaller size, the new variety did not otherwisecorrespond to the characteristics of "Jacaranda", but nevertheless,achieved a new and distinct combination of characteristics which isdesirable and attractive, as well as different from anything heretoforeavailable, as evidenced by the following characteristics which areoutstanding in the new variety:

(1) a medium-sized soft pink flower

(2) very rapid flowering cycles

(3) distinctive fragrance

(4) a vigorous upright plant of medium height

(5) very glossy foliage

The foregoing characteristics and distinctions definitely differentiatethe new variety from its parents, as well as from all other varieties ofwhich I am aware, and asexual reproduction of the new variety bycuttings, grafting or tissue culture as performed in a greenhouse in DeKwakel, the Netherlands, shows that these characteristics anddistinctions come true to form and are established and transmittedthrough succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWING

The new variety of rose plant is illustrated by the accompanyingphotographic illustrations, of which

Sheet 1 shows a full face view of the flower and

Sheet 2 shows typical specimens of the vegetative growth and flowers ofthe new variety in different stages of development. The color renditionsare as nearly true as as it is possible to make same in colorillustrations of this character by conventional photographic procedures.

The following is a detailed description of this new variety, with colorterminology in accordance with The Royal Horticultural Society ColourChart (R.H.S.C.C.). The terminology used in the colordescription hereinrefers to plate numbers in the aforementioned color chart e.g. "53A" isplate "53A of The Royal Horticultural Society Colour Chart.
